The cost of your ticket doesn't always add up to the cost of your trip. Hidden fees for checked baggage, meals, pets, unaccompanied minors, or even seat locations can add up and get you spending more than you thought. Here's a chart that details the fees between 15 different US airlines.

This isn't the first time we've compared airline fees, but this chart from Kayak—your favorite travel site—is one of the most comprehensive and easy to read yet (though it may not be the prettiest). We wish they'd keep track of a few other fees, like in-flight Wi-Fi, but it's pretty detailed as-is. Hit the link to see the full chart.
